“Why have you done this to us, Ambassador?” - The Throat of the Mother

A union between the dormant biomass of an inert changeling and a living subject serves many strange purposes.

Stretch Arm-long - The introduction of inert changeling biomass has brought the ability to bend one’s form further than before, allowing its recipient to extend their limbs up to 15ft, and increase their melee attack range accordingly.

Spare Parts - Given the abundance of biomass available to the body, the transfused’s natural recovery increases rapidly, allowing the recipient to recover 1d8 HP per turn unless damage was dealt with Fire, Acid or Frost.

Dense - The newly ingested biomass brings its recipients to double their previous weight.
